How far can a 4-20ma signal be run

WebMany 4-20ma transmitters claim to be operational between 10 and 30VDC. This can be somewhat misleading. If it’s a two-wire (line powered) transmitter and it is sourcing its maximum loop current of 20ma, 5VDC is dropped across the 250 ohm resistor. E = I x R = 20ma x 250 ohm = 5VDC That only leaves 7 volts to operate the transmitter. Web18 mei 2024 · Multiple 4-20ma sensors cabling. I am planning on wiring 8 x 4-20ma 2 wire sensors to a PLC.
